Profit margins are perhaps the simplest and most widely used financial ratios in corporate finance. A company's profit is calculated at three levels on its income statement, starting with the most basic â gross profit â and building up to the most comprehensive â net profit.
Calculating Gross Margin. Assume your revenue for a given month is $200,000. If your costs of goods sold are $120,000, your gross profit equals $80,000. To calculate your gross profit margin, you divide the $80,000 in gross profit by the $200,000 in revenue. The result is .4, which multiplied by 100 equals 40, or 40 percent. Thus, your gross margin for the period is 40 percent.
